IMPROVEMENT IN RAILROAD-GAR HEATERS.

TO ALL WHOM IT MAY concerns:

Be it known that I, ALBE R'I C. MINER, of city and county of, Philadelphia, and State of -Pennsylvania, have invented a new and useful Improvement in Railroad- Gar Heater and Fire-Extinguisher and I do hereby declare the following to'be a clear and exact description ofthe nature'ther'eof, sulficientto enable others skilled in the art to which myinve'ntion app'ertains to fully understand and use the same, reference being bad. to the accompanying drawings, making part of this specification, in Which- Figure 1 is a longitudinal vertical section of a passenger-car.

' Figure 2 is a transverse vertical section thereof.

Figure 3 isa plan of the floor thereof. I

Similar letters of r'eferenceiindicate corresponding parts in the several figures.

The nature of my invention Consists in the application of steam to railroad-cars, for the purpo'se'of warming passenger-cars, which result is accomplished in a manner as will be hereinafter more fu'lly described.

i In the drawings, A represents a, ba.ggage or mail-car,and A thc floor thereof, and underneath which is placed the steam-service pipe B, having br anch'p ieccs B, into which the tube B and the valve branch-pipes are-screwed. V I

B represents the branch-pipes which .lead into the car.v Suitable stop-cocks or valves 0 are employed to regulate the'supply of stcam'in the car,'and stop-cocks or valves 0' regulate'the supply oi'steam to the s'e rviccpipe or train. i f V The series of steam-pipes will be connected togetheriby flexible pipes D, whose ends are held by couplings D,

The parts thus described, with the exception of valvesd), are also applied to the passenger-car E, represented infig. 3. Onthe floor of this car, I place longitudinally, a stcam bo'x, E, which should be constructed of cast iron, or other'suitable metal, and extend the entire length of the car. I

The pipes 13 open into the box, and admit steam therein. The top o fthe box should be a little below the level of the floor of the car, and on this top I place o metal floor, e whose upper face is corrugated or fluted transversely, and should be iiush with the lloor of the car. This corrugated floor serves topro tect the feet of passengers, when walking along the aisles 5f car.

Suitable ventilating-holes should be made in the box to permit theheat from the sides and bottom. tlie'r'eof to pass up into the car, and thereby provide against the loss of heat.

. Now, inorder to heat the cars, the valves C are opened, and the steam will enter the pipes B, andrcirculate in the box E, while the heat will radiate from said box and diffuse itself throughout the. car.

A small steam-box can be placed at one end of the mail and bsggag'e-cars, in order to warm said cars, but Imay employ bones of the entire length of those cars; 5 v

Since there will be no stoves in the passengcr-cars, the grcatcstdanger from fire to the train will be from the furnace of the locomotive. Thehaggage and mail-cars are naturally the first exposed. Fire soon. is communicated to them, in view of the combustible nature of the mails and trunks. v i V In order to extinguish any fire that may thus occur, I design to inject the steam directly into said cars. For this purpose the pipes B open into the cars, and are provided with light cap-valves b. These valves lie on the pipes and close them'whcn the steam is not admitted, and are flush with the. floor.

Incase'of fire in the baggage or mail-car, the stop cocks QC are turned on, and the steam immediately blows open the valve 6, fills the car, and thus subdues or extinguishes the fire. p

A safety-valve will be secured-to the main pipe, under the tender, and a suitable gauge will be within sight of the engineer, so that the pressure of steam for the cars will be always known, and may be regulated accordingly. 7 r

Havingthus described myinvention, what I claim as ncw,and desire to secureby Letters Patent, is-

lhe steam-box E,having its upper face corrugated, and forming .the floor of the car E, in combination with the pipes B B B and valves 0 C,'-when constructed and operating asherein represented and described.

In testimony whereof, I have signed my nameto this specification in the presence of two subscribing witnesses ALBERT MINER.
